I was looking at stirrers since maintaining the pump on my ReefTek reactor was not fun especially when it’s hard to understand when it’s not working (runs 1 min 4x a day) with 4.5cups of Kalk for around 200g evap, 4-5g a day in the winter. Usually replaced every 2 months. It’s a lot of Kalk but my maintenance schedule on the 600g system is optimized for 2month minimum maintenance schedules.

So after my pump crapped out and I couldn’t find a replacement body for the old MP600. I decided to turn my planned ATO into a Kalk reactor.
I used a Quiteone 6000 I had laying around 1900gph. And some fittings. I run it for 2min 4x a day. Might drop that to 2x a day since my old reactor only held 2g and needed to be stirred more often.

There is open air to the reactor. However potency should be acceptable still at 1.5 tsp per Fresh gallon. Randy has a great article for those who haven’t explored this much.

Also, since it’s in my filter room. This reduction in potency does reduce CO2 in the nearby area (likely useless but I’ll keep it here for comment) - noting that calcium hydroxide / Kalkwasser granules are what you use in the all to famous CO2 scrubbers.

So, do you have a freshwater reservoir, that is pumped into the reactor that is filled with kalkwasser? And what is pushed out of the reactor is a clear solute?

I have the RODI setup on a RO buddy that has a plug controller via Kasa smart plug nuts schedule is 3x a week and fills up the various containers, including the Kalk. The dose is 4g a day right now, 15L a day through an APEX DOS. that will drop in the summer though.

For 1.6g of Kalk per gallon of saturated Kalk I add about 5 cups of Kalk for 2 months. Have an apex reminder on that. The trident shows the loss of alk as I get close to the 2 month mark and adjust seasonally as needed.
